Specification of Letters Patent;

I atented June 16, 1914.

Application filed January 17,-1914.- Serial No. 812,627.

To all whom it may concern:

Be it known that 1, ROBERT E. ELICK, a citizen of the United States, residing at Springfield, in the county of Greene and State of Missouri, have invented a new and useful Triple-Valve-Grinding Machine; and 1 do hereby declare the following to be a full, clear, and exact description ofthe invention, such as will .enable others skilled in the art to which it'appertains to make and use the same.

This invention relates to a new and useful improved grinding machine, the grinding elements thereof'being of a reciprocating character, for grinding a multiplicity of services of several objects, for instance, the cylindrical valve seats of triple valve casings or bodies However, for the purpose of simplicity of illustration, the machine is illustratedas grinding the cylindrical surface of a cylinder shown in dotted lines, but any other suitable object may be ground as well.

in practical fields the details of construction, the proportions, as well as the adaptation or the use of the machine may be subjected to alterations, falling within the scope of what is claimed.

The invention comprises further features and combination of'parts, as hereinafter set forth, shown in the drawings and'claimed.

llnthe drawings :Figure 1 is a view in end elevation of the improved machine constructed in accordance with the invention. Fig. 2' is a front elevation of the same. Fig. 3 is a plan view. Fig. 4 is a vertical sectional view. Fig. dis a sectionalview on line 5-5 of Fig. 4. Fig. 6 isa sectional view on line 6-6 of Fig. 1;

Referring more particularly to the drawings, 1 designates the end standards or ca' ings, on which the base member 2 1s bOlL d or otherwise securedat 3. This base member 2 is recessed at 4 to receive the upper ends of the standards, there being a longitudinal flange 5 overhanging said standards.

This flange 5 not only extends longitudinally of the base member 2, but also transversely ofthe endsthereof. A supplemental base member 6 is provided having a recess '2' to receive the base member 2, there being longitudinal and transverse flanges 8- and 9 overhanging the base member 2. This supplemental base member 6 is provided with bolts 10 passing into the ears 11 of the base member 2, thereby securely mountmg the supplemental base member 6.

The ends of the supplemental base membe]: are provided with upwardly and rear wardly extending arms 12, in bearings 13 of which a crank shaft 14 is mounted, there being a collar 15 to prevent longitudinal movement of the shaft and a pulley 16. to which suitable power (not shown) may be belted.

Rising from and bolted or otherwise secured to the supplemental base member as shown at 17 are standards 18 reinforced by the braces 19 secured to the standards 18 at 20. Mounted in bearings of the standards 18' is a suitable rock shaft 21, and secured to the same as shown at 22 to rock therewitlfis a long arm 23provided with a balancing weight 24 adjustably mounted thereon. Connected at one end to the free end of the arm 23, as shown at 25, is a pitma-n link 26, the other end of which is pivoted to the crank 27 of the shaft 14. Fastencd to the rock shaft 21 as shown at 28 to rock therewith is a plurality of short arms 29. Upon each short arm 29 is an adjustable clamp 30, thy loosening and tightening the bolt 31 of lwhich, the clamp 30 may be adjusted toward tor from the rock shaft, and in so doing adijust'th'e reciprocating member 32 in its re- 'ciprocation. The reciprocating member 32 has a link connection 33 to each of said clamps.

Bolted to each end of-the base member 2 on one side thereof and to each standard is a bracket support Set, the bolting connections are designated by the character 35. Bolted or otherwise secured at 36 to the brackets is a bed plate 37 having a series of cylindrical guide tubes 38, through which the reciprocating members 32 are guided. These guide tubes are threaded at 39 into the bed plate.

The bed plate is provided with a series of to be ground-are seated. For the purpose of illustration, these objects are merely cylindrical collar members shown in dotted lines. However, any other form or shape of object having one or a multiplicity of. cylindrical valve seats may be ground, for instance, such as; triple valve casings or bodies (not shown). Clamping plates 42 are adjostably clamped at 43 to the bed plate, for holding a multiplicity of objects flanged openings 40, in which the objects 41 of other bodies on the bed plate, particularly in said flanged openings.

Carried by the upper portion of the reciprocating member 32 is an arm 44, which may be adjusted vertically upon the member 32, and held adjusted by means of the cap screw or bolt 45. The end portions 46 of the arms 44 terminate in split clamping ends 47, between which grinding tool holders are clamped, by means of the screws 48 having the hand wheels 49. Upon the lower ends of said reciprocating members 32 arms 50 similar to the arms 44 are carried, being adjustable pivotally on the members 82, by loosening and tightening the cap screws 51. Threaded through the split ends 53 of the arms 50 are grinding tool holders 54. These holders 54 may be adjusted by screwing the same in one direction or the other, and after being adjusted the cap screws 55 may be tightened, to draw thesplit ends 53 together, thereby preventing the holders 54 from displacement. It will be noted that the arms 44 may be adjusted vertically, in order to permit grinding tools of various lengths to be clamped between said holders. Furthermore, said arms 44 as well as the arms 50 may be adjusted in so far as the peripheral position of said arm 1s concerned. For instance, after grind ng the large spots from one side of the cylindrical surface of the object 41, the arms 44 and 50 may be adjusted. to bring the tool adjacent the opposite side of the cylindrical surface of said object. Furthermore, it will be noted that one set of arms 44 and 50 and their holders may carry a grinding tool of one length and a different shape otherwise, for grinding a greater length of cyllndrical surface, while each of the other sets of arms and their respective holders may carry a different length of tool and vice versa. Further, it will be observed that by adjusting one or another of said clamps 3O closer to the rock shaft 21 or outwardly therefrom, the multiplicity of tools may receive reciprocations varying in length, one tool may be grinding one side of a cylindrical surface, while another tool may be grinding another portion of a cylindrical surface of another object. In other words, none of the tools singly or collectively are required to reciprocate alike, and may be adjusted independently and individually.

The invention having been set forth, what is claimed as new and useful is 2-- p 1.
